Case statements which terminate with multi-line return statements

If a case statement terminates with a return, and if the return has multiple lines, then it produces an error -- "Case breaking statements must be followed by a single blank line" -- even if there is a blank line.

I've posted an example at https://gist.github.com/totten/5f14b5a941e5a9daeafe . (I tried posting here, but the preview comes out a little wonky.)
